And -40 degrees C = -40 degrees F. And then there is absolute temperature, degrees Kelvin and Rankine.

what MM socket is

Or take 20 C, multiply by 2 to 40, take off 10% = 36; add 32 = 68 F
Or take off 10% from the initial C reading of 20 = 18; multiply by 2 = 36, add 32 = 68 F
Saves having to do "long division/multiplication if you do not have enough fingers or matchsticks!!! Dave_n
The only one I remember is that -40 =-40. Useful occasionally in MT.

Did not specify if right or left handed Crescent needed as well.
Doesn't matter. He can always turn it over and use the other hand.
Being old and hard headed, I resisted the metric push for years. A few years ago I was getting ready to build a (very fancy) hunting blind and, on a whim, decided to build it totally metric. As hard as it is to admit, it was a lot easier, faster, and more accurate than the inches method. It was so nice to measure without fractions. Since that discovery, everything I build from scratch gets built metric. Not sold yet on the other metric measurements.

I have a set of Whitworth/BSF sockets from Snap-On. I can count on my fingers the times I have needed them in 40-odd years, but when I did need them, I really needed them. I never could justify adding a corresponding spanner set from Abingdon King Dick.
Snap-On six-point sockets will often work quite well on fasteners from the other systems. The ends of the flats are relieved at the corners so that the socket always bears on the flat of the fastener, never the corner. Called Flank Drive, it is the reason Snap-Ons will loosen fasteners that other wrenches will just round off. Metrinch tools work on the same pribciple, but the purpose there is to give a sloppy but effective fit on fasteners from any corner of the universe.

My metric 250mm Crescent wrench is right handed, but I have two 300mm, One is Right and one is ambidextrous. (My 8, 6, 4, 3 inch Crescent wrenches are older and only usable on standard American bolts)
In my grandfather's watch & clock repair tool kit there were a 1.5" and a 1.25" adjustable wrenches of the "F" pattern. He told dad years ago so, many watches and clocks have hand made nuts and bolts that there where no standard wrenches! (Oh how I wish I had granddad's tool kit!, gone to dad's second wife's hillbilly nephew!)

I have an adjustable wrench (bacho spl?) that came from Sweden; the problem for me is the adjustment wheel requires the opposite direction (compared to a Crescent brand) to close the jaws and messes me up. So it remains unused in a seldom used drawer in my tool box.
No brainer.

If you work on any car foreign or domestic you now need metric wrenches. I have a tool box that has metric sockets in 1/4, 3/8 and 1/2 drive. A set of metric swivel sockets (Try getting the back valve cover bolt off a Ford Power-stroke without one). Metric wrenches, short. lock and ratcheting and a couple sets of metric Allen wrenches. I even have a set of 1/2" metric impact sockets. Its the way of the world now.
If your an occasional mechanic you can pick up a set of wrenches, 3/8 sockets, deep and shallow, plus a set of Allens for under a $100. Places like O'Reilly, CarQuest, even Harbor Freight is you don't take the bottom end stuff. Make sure the sets you get don't skip some sizes. Some sets skip sizes like the 11mm or 16mm. For some reason manufactures think we need from everything from 6mm to 25. Why some bolts of the same thread take a 14 when most take a 13 is beyond me, But that's the way it is.
If at all possible get 6 point sockets. Less apt to slip and round off with them. Of course then sometimes some genius of an "engineer "decides to use a stupid 12 point bolt head and then you need that 12 point socket.
PS 61 cubic inches equals 1000cc. 1000cc=1 liter. . A 5liter motor is a 305 cu in. But they round up and down a bit. A 302 Ford is also called a 5 liter. I remember because the 61 cu in Knucklehead engine was 1000cc.
3 liter=183
4 liter=244
5 liter 305
5.7 liter =350
6 liter 366
7 liter 427
7.3 liter=445

Can you judge the age of a woman in Metric?
Some friends from Australia give their weight in "Stone". My Brother raises horses, his wife's height is in "Hands". When we bought barbed wire for any of our farms it was in "Rods". Gun chamber pressure used to be in Copper or Lead Pressure Units (CPU or LPU) for America and TONNES for English. Torque was in Foot Pounds or Inch Pounds, now I see, several including: Newtons and Kilopascals (and the shade tree equivalent: "Just about there/oops!")

100 Kilo pascals equals 15 psi. I once drilled on a Canadian drilling rig and its pressure gauges were metric. That is a pressure measurement, not torque
They measure torque in Nm (Newton meters) 100Nm=73.8ftlb. Going with 100=75 isn't going to hurt anything. The Canadian rig also had a metric torque gauge on one set of tongs for making up drill collars. 6 1/2" collars weight about 90# to the ft and torque up at about 30,000ftlb. Thats there is tight and a string of 24 30' long is heavy (about 65,000#) Interestingly the weight indicator was in pounds. Drill collars are the weight used on the drill bit, the rest of the pipe is just to pump the drilling fluid though and act as a drive shaft, unless you go directional and then they put a hydraulic motor just above the bit and turn it with the mud pressure. (up to 7,500 psi (52,000 kPa).
Drilling rigs are how I miss spend a lot of my 20s and early 30s

Ah metric women.
Ok, 1 stone is about 14 lg so 7-9 stone is about 100 to 128.
152centimeterss is almost 5' and 183 is 6'
24" is 61c
36" is 91.5c
The red haired metric ones are great just like their SAE cousins
Cold
1.8f=1c or 1f=.555c
-40f=-40c (been there done that)
-20f=-29c
0f=-17f
10f=12c
32f=0C
50c=10c
70f=21c
90f=32c
and your hot tub should be about 38c or 100f
But I have a hard time "thinking" in Celsius, no problems with measurements, I just remember that a meter is about 39 inches, 100 meters is 110 yard. A kilometer is .62 miles and a mile is 1.6 meters
A kilo is 2.2 LB and a ton is 909#.

I had shop class in 1962. If we called it a crescent wrench our shop teacher would correct us, "it is an open end adjustable wrench made by the Crescent Tool Company" We soon learned so we didn't have to hear him over and over.

I agree - now all my DIY carpentry projects are metric. So much easier than trying to convert fractions.
The other day I needed to use a 9/16" wrench. It was probably the first time in 2 yrs I had used my fractional wrenches. My metrics are used every week.

My wife is about 180cm and about 68kg. If stone are equal to 14 American pounds the she would be around 11 stone. (I wonder what Sharon Stone weighs?)

I agree. I'm a retired scientist, so I've been using the metric (properly, the "SI", as I'm sure you know) system for most of my life. I love my country, but we sure have difficulty with change, as do (apparently) Myanmar and Liberia, the only other countries in the entire world that don't use the metric system. And it's not just measurement - consider the difficulties encountered in dropping the $1 bill in favor of a $1 coin, or getting rid of the penny, which serves no useful purpose whatsoever.
Also, the so-called "Gimli Glider", an Air Canada 767 that ran out of fuel at 41,000 ft because of an incorrect metric/English conversion during refueling. Thankfully, the pilot was also a glider pilot and managed to land it safely at a decommissioned air base in Gimli, Manitoba. Full story here: Gimli Glider - Wikipedia

And remember, in Amsterdam, you can’t even get a Quarter Pounder with Cheese. Because of the metric system.
Funny that you named two of the sizes that we do not need. For all practical purposes an 11 is a 7/16", difference 0.0025", and a 16 is a 5/8", difference .0049". Never having found a foreign car bolt that takes a 16 I figure the reason 16s are common in wrench sets is so the manufacturer does not have to manufacture a useful 17. they just stamp some of their 5/8" wrenches 16. The same is true of 19s which are only 0.002" different than 3/4". Since I've never found a use for a metric wrench smaller than 8 I conclude those are thrown in so the manufacturer can boast their cheap set has 40 pieces.
8, 10, 12, 14 and 17 are all a Toyota driving "occasional mechanic" needs. 21 does the spark plugs and lug nuts but so does a 13/16". 11, 13 and 15 are for Honda drivers and Hondas are for people who want their valves driven through the tops of their pistons every time a rubber band breaks.
